The real value to me of searching with images would not be either for directions or movies, but when one needs to find a particular image or an image of a particular thing. For instance, I do trademark research, and in order to search the USPTO database of logos, you have to be able to describe the image in terms of their specific and limited vocabulary and numeric codes. This is amazingly time-consuming and sometimes quite difficult when the image is a non-standard shape and not representational. If I just plug in the image and say 'Find all the ones that look like this,' it would be a heck of a lot easier.
